摘要
以贵州省内11个无籽刺梨产地土壤为研究对象,测定其容重、田间持水量、p H值、有机质、全氮、全钾、全磷、有效磷、水解氮和速效钾等10个指标,采用土壤质量评价指数分析各产地的土壤现状与差异。结果表明:1)11个产地间的土壤理化性质存在较大差异,Z值中心聚类将11个无籽刺梨产地分为2类;2)11个产地的土壤评价指数的排序为:QY>JC>SC>NG>SP>HL>HF>XY>XB>YZ>LG;全磷、全氮和土壤容重指标是贵州省无籽刺梨产地土壤质量的主要影响因子。
In this study, soil bulk density, field capacity, pH, organic matter, total nitrogen, total potassium, total phosphorus, available phosphorus, hydrolyzed nitrogen and available potassium of Rosa sterilis soils from 11 Karst regions collected were analyzed. The aim was to evaluate the soil status of R. sterilis regions based on soil quality index. The results showed that： 1 ） The soil physical and chemical properties were greatly different from among different regions. Besides, the clustering analyze divided the regions into two groups. 2） The evaluation of soil quality index was ： QY 〉 JC 〉 sc 〉 NG 〉 SP 〉 HL 〉 HF 〉 XY 〉 XB 〉 YZ 〉 LG ;Total phosphorus, total nitrogen and soil bulk density are the primary factors of R. sterilis soil in Karst regions.
